What energy carriers can enter the electron transport chain in mitochondria to generate ATP?
ElenaW [278]

Answer: The electron transport chain consists of complexes which are the proton pump for the hydrogen ions across the mitochondrial membrane which allows the synthesis of the ATP (energy currency).

Explanation:

The electron transport chain occurs in the mitochondria. ATP synthase present in the inner mitochondrial membrane is a carrier of electron. FADH2 AND NADH two molecules supply high energy electrons from the citric acid cycle from the electron transport chain at complex I (NADH coenzyme Q reductase) and II (succinate dehydrogenase)respectively.

When does the chunk of ice have the most potential energy?
klasskru [66]

An enormous rift in one of Antarctica’s largest ice shelves grew dramatically over the past month, and a chunk nearly the size of Delaware could break away as soon as later this winter, British scientists reported this week.
